EV owners of today and tomorrow

Don't worry, we'll forget about ...

soon enough

Kinda like all the hearings, one news cycle and it’s all over?

For some reason this is only an environmental disaster because it is an EV factory. Forgetting things like Deepwater Horizon, numerous refinery fires, fertilizer plant fires, grain mill fires, or even a fire at a J.M. Smucker Peanut Butter Plant.

Not the peanut butter! Bet that one smelled damn good, tho.

I think you all are feeding the douche (Tradasaurus). Amazing that the mods haven’t shut this down based on his insults to other members. No way to get a two way dialog with Trad and Grumpy (the alias egos).

I think it's unfair to throw Grumpy in with Tradasaurus. Grumpy may be grumpy, but he at least posts useful information, that is worth debating.

How can the pieces of a catalytic converter get tucked into the engine from the exhaust side???

There is a net positive pressure at the tailpipe, but I do believe there are localized flow reversals at each header port, as each piston cycles. Specifically, I think there's a period of low relative pressure immediately after the exhaust valve closes, which has the potential to cause momentary flow reversal.

In an exhaust manifold, I suspect the flow reversal at one piston is supplied by the positive pressure of an adjacent piston connected to the same manifold. But in the situation of exhaust headers having long segregated runs to the collector, then I suspect it's just as likely the reversal could be supplied from the collector. I'm still honestly surprised the wavelength (think longitudinal sound pressure waves) could be as long as a header run, but if the car manufacturer happened to make several consecutive very bad design choices (header tube length, collector length, cat position), then it could theoretically add up to particles shed by the combustor getting sucked back into a piston.

Seems very unlikely, but perhaps theoretically possible. I also don't think it is happening with anywhere near the frequency to affect the overall reliability, with respect to the list I posted, and to which this supposed "problem" was posted in response.

If that poster didn’t attempt to abuse others, I’d tend to agree.

Citation required. Or shut up.

But it doesn't matter! The "study" said what DarkBlack wanted to hear.

Kablam! DB can't stand the fact that we drive superior vehicles and are just plain awesome people for driving Teslas.

 

[tradosaurus]

You know, I think exactly the same thing is hindering adoption of cellphones, laptops, tablets, and battery power tools!

Hilarious. Kablam!
I remember when cell phones had all sorts of charging cords with different ends.

Citation required of his abusive posts and just plain pot stirring of ignorance.

...Or shut up.

Exhibit 'A'.

Assuming that was posted as a joke.

The previous poster linked JD Power with Tesla at the bottom.
I posted Consumer Reports showing Tesla mid-pack. Thought I was actually being kind….

You’re blaming me for Consumer Reports rating?
You think I work for Consumer Reports?

Taking no sides and likely some may say this report is biassed in some way.

Beyond the Sticker Price: The Cost of Ownership of EVs v. ICE Vehicles

Price is always a significant factor in choosing a new vehicle, as is the total cost of ownership. Combining purchase price with a cost of ownership estimate has always been a helpful way to evaluate whether a certain vehicle is right for an individual, especially when thinking about cost in...
